Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, an edge brush structure 100 of a sweeper truck according to an embodiment of the present application includes: a main shaft 110 and at least one edge brush assembly 120. The main shaft 110 is used to connect the edge brush structure 100 to the sweeper. The main shaft 110 and the side brush assembly 120 are connected with each other through the first anti-collision assembly 130 and the second anti-collision assembly 140 in sequence. Wherein the second collision avoidance module 140 is rotatable relative to the main shaft 110 via the first collision avoidance module 130. The edge brush assembly 120 is capable of movement relative to the first bumper assembly 130 through the second bumper assembly 140 to a range that allows the edge brush assembly 120 to tilt in multiple directions relative to the first bumper assembly 130. The first and second bumper assemblies 130, 140 include first and second rebound mechanisms 131, 141, respectively. The first resilient mechanism 131 is capable of acting on the main shaft 110 to store energy for resetting the first collision avoidance assembly 130. The second resilient mechanism 141 is capable of acting on the side brush assembly 120 to charge energy for resetting the side brush assembly 120. With the first and second impact prevention assemblies 130 and 140, the side brush assembly 120 can rotate or tilt in multiple directions relative to the main shaft 110 when an external force is applied thereto, and can rebound to an initial position after the external force disappears.
The main shaft 110 is connected to the sweeper. The side brush structure 100 is connected to the main shaft 110, thereby enabling the main shaft 110 to connect the side brush structure 100 with the sweeper. The connection between the main shaft 110 and the sweeper can be a fixed connection or a movable connection according to the actual application requirements.
The number of the side brush assemblies 120 is at least one. Generally, as shown in fig. 1, the number of the side brush assemblies 120 is two, and the two side brush assemblies 120 are respectively disposed at two ends of the main shaft 110 and located at the same side of the main shaft 110, and are symmetrically disposed.
The first bumper assembly 130 and the second bumper assembly 140 are connected between the main shaft 110 and the side brush assembly 120, and the main shaft 110, the first bumper assembly 130, the second bumper assembly 140 and the side brush assembly 120 are sequentially connected. The first bumper assembly 130 functions to allow the second bumper assembly 140 and the edge brush assembly 120 to rotate relative to the main shaft 110. The second bumper assembly 140 functions to enable the edge brush assembly 120 to tilt relative to the first bumper assembly 130. The edge brush assembly 120 can rotate or tilt in multiple directions relative to the main shaft 110 by sequentially connecting the first collision avoidance assembly 130 and the second collision avoidance assembly 140.
The first bumper assembly 130 includes a first resilient mechanism 131. The first resilient mechanism 131 can act on the main shaft 110 to store energy, and when the second anti-collision assembly 140 and the side brush assembly 120 rotate relative to the main shaft 110, a force opposite to the rotation direction of the second anti-collision assembly 140 and the side brush assembly 120 can be generated to drive the second anti-collision assembly 140 and the side brush assembly 120 to return to the initial position.
The second bumper assembly 140 includes a second rebound mechanism 141. The second resilient mechanism 141 is capable of acting on the side brush assembly 120 to store energy, and is capable of generating a force opposite to the rotation or movement direction of the side brush assembly 120 when the side brush assembly 120 rotates or moves relative to the first bumper assembly 130, so as to drive the side brush assembly 120 to resiliently return to the initial position.
According to the side brush structure 100 of the sweeper, the first anti-collision assembly 130 and the second anti-collision assembly 140 are arranged between the main shaft 110 and the side brush assembly 120, so that the side brush assembly 120 can rotate or incline towards multiple directions when being impacted forwards or laterally, and the protection of the side brush assembly 120 in more directions is increased. The first and second rebound mechanisms 131 and 141 are further disposed in the first and second anti-collision assemblies 130 and 140, respectively, so that the side brush assembly 120 can rebound to an initial position after the external force disappears after being rotated or tilted by a force, thereby facilitating subsequent operation control. The sweeper limit brush structure 100 in the above scheme not only can enable the limit brush assembly 120 to rotate in multiple directions, but also can enable the limit brush assembly 120 to timely return to an initial position, and compared with a protection structure arranged on the limit brush assembly 120 in the prior art, the limit brush structure is wider in application range, can be suitable for more complex environments, and timely rebounds after the limit brush assembly 120 rotates under stress without influencing subsequent operation control.
Referring to fig. 2 and 3, in a specific arrangement, the first anti-collision assembly 130 includes: a rotating base 132 and a rotating bracket 133. Wherein, the rotating base 132 is fixedly connected to the main shaft 110. The rotating bracket 133 is rotatably connected to the rotating base 132 by a first connecting shaft 134, so that the rotating bracket 133 can rotate about the first connecting shaft 134 relative to the rotating base 132.
It should be understood that the rotating base 132 is fixedly connected to the main shaft 110, which means that the rotating base 132 is fixed in position relative to the main shaft 110 during normal use, and does not generate displacement, and is not limited to the rotating base 132 and the main shaft 110 being connected together, and the two may be detachably connected by a screw connection or the like. In the present embodiment, in order to ensure the strength of the connection position between the rotating base 132 and the spindle 110, the rotating base 132 and the spindle 110 are connected by welding.
In a specific arrangement, as shown in fig. 3, the first connecting shaft 134 is vertically arranged, so that the rotating bracket 133 can rotate around the first connecting shaft 134 relative to the rotating base 132, and the rotating bracket 133 rotates in a plane parallel to the ground.
In a specific arrangement, the axial direction of the first connecting shaft 134 is perpendicular to the axial direction of the main shaft 110. The rotating bracket 133 rotates in a plane perpendicular to the axial direction of the first coupling shaft 134.
Referring to fig. 2 to 4, in a specific arrangement, a limiting mechanism 135 is disposed between the rotating base 132 and the rotating bracket 133. The limiting mechanism 135 comprises a limiting column 1351 and an arc-shaped groove 1352, the limiting column 1351 and the arc-shaped groove 1352 are respectively arranged on the rotating base 132 and the rotating bracket 133, and the limiting column 1351 and the arc-shaped groove 1352 are in sliding fit.
In the embodiment, as shown in fig. 4, the position-limiting post 1351 is fixedly connected to the rotating base 132, the arc-shaped slot 1352 is opened on the rotating bracket 133, and the axial direction of the position-limiting post 1351 is parallel to the axial direction of the first connecting shaft 134. The arc-shaped groove 1352 penetrates through a plane of the rotating bracket 133, which is in contact with the rotating base 132, the limiting column 1351 is inserted into the arc-shaped groove 1352 and is in sliding fit with the arc-shaped groove 1352, and the circle center of the arc-shaped groove 1352 is consistent with the rotating axis of the rotating bracket 133, so that the limiting column 1351 slides in the arc-shaped groove 1352 when the rotating bracket 133 rotates.
Referring to fig. 2 and 3, in a specific configuration, the first resilient mechanism 131 includes an elastic member 1311 and an adjusting mechanism 1312, the adjusting mechanism 1312 is connected to the main shaft 110, the adjusting mechanism 1312 includes an adjusting member movably disposed with respect to the main shaft 110, one end of the elastic member 1311 is connected to the rotating bracket 133, and the other end is connected to the adjusting member (the connection state is not shown).
It is understood that the elastic member 1311 is coupled between the rotating bracket 133 and the adjusting member. Wherein the position of the adjusting mechanism 1312 and the adjusting member is fixed relative to the main shaft 110 during use, and when the rotating bracket 133 rotates relative to the rotating base 132 around the first connecting shaft 134, one end of the rotating bracket 133 near the main shaft 110 will displace relative to the adjusting mechanism 1312. During the installation of the elastic member 1311, the position of the adjusting member with respect to the main shaft 110 may be moved to set the length of the adjusting member according to the elastic adjustment of the elastic member 1311.
Referring to fig. 3 and 4, when the rotating bracket 133 is located at the initial position, the rotating bracket 133 is pulled by the elastic member 1311 and cooperates with the limiting mechanism 135, so that the rotating bracket 133 is kept at the initial position under a certain pre-tightening force. Specifically, when the rotating bracket 133 is located at the initial position, the rotating bracket 133 is pulled by the elastic member 1311, so that the rotating bracket 133 tends to rotate in the direction of the pulling force of the elastic member 1311. The positions of the limiting columns 1351 and the arc-shaped grooves 1352 at this time are as shown in fig. 4, the limiting columns 1351 are located in the arc-shaped grooves 1352 and at an end of the arc-shaped grooves 1352 opposite to the rotation tendency of the rotating bracket 133, so that the pulling force of the elastic member 1311 on the rotating bracket 133 is counteracted by the acting force between the limiting columns 1351 and the arc-shaped grooves 1352, and the rotating bracket 133 is maintained at the initial position in a state of being subjected to a certain pre-tightening force.
Referring to fig. 3 and 4, at this time, the position-limiting post 1351 can only move along the arc-shaped groove 1352 in the pulling direction of the elastic member 1311 inside the arc-shaped groove 1352, and therefore, the rotating bracket 133 can only rotate in the direction opposite to the pulling direction of the elastic member 1311. When the side brush assembly 120 is forced and drives the rotating bracket 133 to rotate counterclockwise around the first connecting shaft 134, the distance between the end of the rotating bracket 133 close to the main shaft 110 and the adjusting mechanism 1312 becomes longer, the elastic member 1311 is stretched, and the end of the rotating bracket 133 close to the main shaft 110 is pulled by the elastic member 1311 and drives the rotating bracket 133 to rotate clockwise around the first connecting shaft 134, so as to achieve the effect of rebounding and resetting the side brush assembly 120.
In one arrangement, as shown in fig. 3, the adjustment mechanism 1312 includes a fixed seat 1313, an adjustment screw 1314 and a nut 1315. The fixing seat 1313 is fixedly connected to the main shaft 110. The adjusting screw 1314 penetrates the fixed seat 1313, and one end of the adjusting screw is in threaded connection with the nut 1315, while the other end is connected with the elastic piece 1311. The nut 1315 and the elastic member 1311 are respectively disposed at both sides of the fixing seat 1313.
It will be appreciated that the adjustment mechanism 1312 functions to adjust the distance between the adjustment screw 1314 and the rotation bracket 133 according to the elastic adjustment of the elastic member 1311. For example, after a long period of use, the elasticity of the elastic member 1311 may decrease with a long period of tension and may not be enough to provide enough pre-tension to the rotation bracket 133 at the initial position, in which case, the distance between the screw 1314 and the rotation bracket 133 can be adjusted by the adjusting mechanism 1312 to adapt to the elastic force variation of the elastic member 1311. During use, the adjustment mechanism 1312 is generally fixedly disposed relative to the main shaft 110 unless the elasticity of the elastic member 1311 changes.
Specifically, during installation, with the edge brush assembly 120 in the initial position, the distance between the adjustment screw 1314 and the rotational support 133 can be adjusted by adjusting the relative positions of the nut 1315 and the adjustment screw 1314. Specifically, when the tension of the elastic member 1311 on the rotating bracket 133 is too large, the position of the adjusting screw 1314 may be adjusted so that the distance between the adjusting screw 1314 and the rotating bracket 133 becomes smaller; when the pulling force of the elastic member 1311 applied to the rotation bracket 133 is too small, the position of the adjustment screw 1314 may be adjusted so that the distance between the adjustment screw 1314 and the rotation bracket 133 becomes large.
Referring to fig. 3 to 4, in a specific arrangement, the first connecting shaft 134 includes a first pivot screw 1341, a first nut 1342 and a spacer 1343. The rotary base 132 and the rotary bracket 133 are both provided with through holes adapted to the first pivot screw 1341. The first pivot screw 1341 and the first nut 1342 are engaged to rotatably connect the rotary base 132 and the rotary bracket 133. The spacer 1343 is disposed outside the first pivot screw 1341 and between the through hole of the rotating bracket 133 and the first pivot screw 1341.
It can be understood that, in general, after the first pivot screw 1341 and the first nut 1342 are coupled to the rotating base 132 and the rotating bracket 133, the first pivot screw 1341 and the first nut 1342 are fixed in position relative to the rotating base 132, and the rotating bracket 133 can rotate relative to the rotating base 132 around the first pivot screw 1341.
It can be appreciated that the spacer 1343 serves to protect the rotational bracket 133 and the first pivot screw 1341 from damage caused by multiple rotational frictions of the rotational bracket 133 and the first pivot screw 1341. In a specific setting mode, can be connected spacer 1343 and swivel bracket 133's through-hole for spacer 1343 and swivel bracket 133 rotate in step, after swivel bracket 133 and first pivot screw 1341 rotated the friction damage many times, only need to be changed spacer 1343 and first pivot screw 1341 can, can reduce the maintenance cost.
As shown in fig. 3, in this embodiment, in order to prevent the first connecting shaft 134 from loosening during use, two washers are further sleeved outside the first rotating shaft screw 1341, one washer is disposed between the rotating base 132 and the rotating bracket 133, and the other washer is disposed between the first nut 1342 and the rotating base 132.
Referring to fig. 3, in a specific arrangement, the side brush assembly 120 includes a brush 121, a side brush mounting base 122 and a rotating motor 123. The rotary motor 123 is mounted on the side brush mounting base 122, and the brush 121 is connected to the rotary motor 123 and is rotated by the rotary motor 123. As shown in fig. 1 and 2, in the present embodiment, the rotating motor 123 and the brush 121 are respectively coupled to both ends of the side brush attachment base 122. The brush 121 is attached to the lower side of the side brush attachment base 122, and the rotating motor 123 is attached to the upper side of the side brush attachment base 122. A transmission mechanism is also provided between the rotating motor 123 and the brush 121. The transmission mechanism penetrates through the side brush mounting base 122, and can drive the rotation of the rotating motor 123 to drive the brush 121 to rotate.
Referring to fig. 2, 3 and 5, in a specific arrangement, the second bumper assembly 140 includes a second connecting shaft 142 and a connecting bracket 143. One end of the connecting bracket 143 is movably connected to the rotating bracket 133 through the second connecting shaft 142 in a multi-directional tilting manner within a certain range with respect to the rotating bracket 133 so that the connecting bracket 143 can tilt in multiple directions around the second connecting shaft 142, and the other end of the connecting bracket 143 is fixedly connected to the side brush assembly 120.
As shown in fig. 3, in the embodiment, the rotating bracket 133 has a step-shaped structure, and an end of the rotating bracket 133 connected to the rotating base 132 and an end of the rotating bracket 133 connected to the connecting bracket 143 are not located on the same plane, which is used for preventing the second connecting shaft 142 from interfering with the rotation of the brush 121.
Referring to fig. 3, in a specific arrangement, the end of the rotating bracket 133 connected to the connecting bracket 143 is further provided with two opposite flanges facing the connecting bracket 143, and the two flanges sandwich the connecting bracket 143 to limit the swing range of the connecting bracket 143. Taking the installation mode of fig. 5 as an example, the connecting bracket 143 is located below the rotating bracket 133, and the flange of the rotating bracket 133 faces downward, so that the connecting bracket 143 is limited by the flange in the rotation plane of the connecting bracket 143. As another arrangement, the connecting bracket 143 may be disposed above the rotating bracket 133, and at this time, the flange of the rotating bracket 133 faces upward, so that the connecting bracket 143 is limited by the flange in the rotating plane of the connecting bracket 143. It should be understood that the flanges may also be provided on the connecting bracket 143, i.e., in other words, the flanges may be provided on either one of the swivel bracket 133 and the connecting bracket 143 to form a clamping limit for the other.
It should be understood that the flanges described herein and the through holes described below in the connecting bracket 143 and the rotating bracket 133 both limit the tilting movement of the connecting bracket 143.
Referring to fig. 3, in a specific arrangement, the second connecting member 142 includes a second rotating shaft screw 1421 and a second nut 1422. The connecting bracket 143 and the rotating bracket 133 are each provided with a through hole for passing the second rotating shaft screw 1421. The second shaft screw 1421 is coupled to the second nut 1422 to connect the connecting bracket 143 and the rotating bracket 133 in a multi-directional tilting manner.
It can be understood that the second rotation shaft screw 1421 sequentially passes through the through holes of the connecting bracket 143 and the rotating bracket 133 and is connected to the second nut 1422, or the second rotation shaft screw 1421 sequentially passes through the through holes of the rotating bracket 133 and the connecting bracket 143 and is connected to the second nut 1422, so that the connecting bracket 143 can tilt in multiple directions along the second rotation shaft screw 1421 relative to the rotating bracket 133.
Referring to fig. 5, in a specific arrangement, the second shaft screw 1421 is in clearance fit with at least one of the through holes of the connecting bracket 143 and the rotating bracket 133. Specifically, the second rotating shaft screw 1421 may be in clearance fit with a through hole of the connecting bracket 143, or the second rotating shaft screw 1421 may be in clearance fit with a through hole of the rotating bracket 133, or both the second rotating shaft screw 1421 and through holes of the connecting bracket 143 and the rotating bracket 133 are in clearance fit.
It will be appreciated that when the second rotation shaft screw 1421 is in clearance fit with the through hole of the connecting bracket 143, the through hole of the connecting bracket 143 will slide along the second rotation shaft screw 1421 when the connecting bracket 143 is stressed. Because the connecting bracket 143 is stressed by an inclined angle and the through hole of the connecting bracket 143 is in clearance fit with the second rotating shaft screw 1421, the connecting bracket 143 will be inclined relative to the second rotating shaft screw 1421. Similarly, when the second spindle screw 1421 is in clearance fit with the through hole of the rotating bracket 133, when the connecting bracket 143 is stressed, the connecting bracket 143 drives the second spindle screw 1421 to tilt in the through hole of the rotating bracket 133.
It can be understood that when the second rotating shaft screw 1421 is in clearance fit with the through holes of the connecting bracket 143 and the rotating bracket 133, the connecting bracket 143 can be inclined at more angles relative to the rotating bracket 133. The inclination angle of the connecting bracket 143 with respect to the rotating bracket 133 is related to the size of the gap between the through hole and the second rotating shaft screw 1421. The larger the gap between the through hole and the second rotating shaft screw 1421 is, the more the second rotating shaft screw 1421 can be tilted in the through hole, and the more the connecting bracket 143 can be tilted with respect to the rotating bracket 133.
In this embodiment, the second rotation shaft screw 1421 is in clearance fit with the through holes of the connecting bracket 143 and the rotating bracket 133. When the side brush assembly 120 is stressed, the side brush assembly 120 will drive the connecting bracket 143 to rotate or move up and down relative to the rotating bracket 133, because the aperture of the through hole of the rotating bracket 133 is larger than the diameter of the second rotating shaft screw 1421, the connecting bracket 143 will drive the second rotating shaft screw 1421 to tilt in the through hole of the rotating bracket 133, and because the aperture of the through hole of the connecting bracket 143 is also larger than the diameter of the second rotating shaft screw 1421, the connecting bracket 143 will move along the tilted second rotating shaft screw 1421, thereby realizing the multidirectional movement of the side brush assembly 120 relative to the rotating bracket 133.
Referring to fig. 5, in a specific arrangement, the second resilient mechanism 141 is a compression spring. The compression spring is sleeved outside the second rotating shaft screw 1421 and is located between the second nut 1422 and the connecting bracket 143 or the rotating bracket 133. Specifically, when the connecting bracket 143 is coupled to the upper side of the rotating bracket 133, the pressing spring is positioned between the second nut 1422 and the rotating bracket 133, or, as shown in fig. 5, the connecting bracket 143 is coupled to the lower side of the rotating bracket 133 and the pressing spring is positioned between the second nut 1422 and the connecting bracket 143.
It can be understood that, when the connecting bracket 143 moves along the inclined second spindle screw 1421, or the connecting bracket 143 does not move along the inclined second spindle screw 1421 but the second spindle screw 1421 is inclined in the through hole of the rotating bracket 133, the connecting bracket 143 generates a pressure force on the compression spring in a direction of compressing the compression spring, and the connecting bracket 143 will rebound to the initial position under the elastic force of the compression spring.
